AttributeError: 'WSGIRequest' object has no attribute 'is_ajax' (is_ajax has been defined in the views.py file)
I have included the following is_ajax() function, so that I can use it in another Django view function in the same views.py file: def is_ajax(request): return request.META.get(‘HTTP_X_REQUESTED_WITH’) == ‘XMLHttpRequest’ However, the problem is that I am still getting the following error message in the terminal: AttributeError: ‘WSGIRequest’ object has no attribute ‘is_ajax’ The following image shows the views.py file where the is_ajax() function is being called on line 48: is_ajax() function in the views.py file line 48 I will appreciate any suggestions on how to resolve this issue. Thank you. -

I am trying to subtract two fields from a model. For example, "Soldfor" is assigned 55 and "Paidfor" is assigned 1.99 in the database.

django rest framework api key How to set view/endpoint permissions by apikey?
I am using django "rest framework api key"; I have urls in my urls.py (I'll try to keep it simple): a/ b/ c/ and I have created api keys; lets say "apikey1", "apikey2" and "apikey3". I can grant permissions for urls "a" and "b" and then "c" wont be accesible by any apikey; but all the apikeys can access all registered urls (or views). What I need is to restrict "apikey1" to only "a/" "apikey2" only to "c/" and "apikey3" access to both. I know I can do it with users by checking authenticated user in the request and then verify aganinst some list; if the user is in my list, keep going, else redirect 400 or whatever. but how do I do that with apikeys? -
Creating printable forms with Python and Django backend
I want to create a Saas website (for our company's internal use, but I don't see why it couldn't be a full service down the line. The service will provide an way for users to create forms for our industry, and there are a lot of legislated forms. Those forms should be able to be exported to PDF to be added to a different client management software as attachments. I am building it with Django/Python/MySQL backend and HTML, CSS, Javascript frontend. My question is this: What would be the best way to produce well-formatted print/PDF forms. My current ideas are: Using pre-designed PDF interactive PDF forms and have the system insert values into the PDF form fields Using the same idea, but with a Word document (although I don't much favour this Ideally, I would like to be able to form the document fully in the backend, but I haven't really found out how to do this. Any ideas would be greatly appreciated - thank you! -

Is it possible to convert these FBVs that return HttpResponse() into CBVs? (Django)
I currently have the following function-based views, their purpose is to take a specific action based on what the user selected: @login_required() @csrf_exempt def remove_member(request, pk, project_id): if request.method == 'POST': user = get_object_or_404(User, id=pk) project = get_object_or_404(Project, id=project_id) project.members.remove(user) html = '<div class="alert alert-success" role="alert" id="message-response">' \ 'Update successful!

' + user.first_name + ' is no longer an admin. </div>' return HttpResponse(html) I'm using htmx on the template to populate a div with the returned html. There are several similar functions to the examples above. So I would like to convert these into a single CBV in order to reduce redundancy. The new CBV would also require some sort of check, in order to take the appropriate action. However, I'm not sure which class would be best suited for this, and which method would be best to override in this scenario. (admin and members are M2M fields assigned to the Project model) -

How would I get sum from all rows, but only output one row? Django and Postgresql
currently the way I have the code written is that I have a model named Finances. I have an aggregate set up so it sums up all of the rows. I am trying to display the outcome of the rows, but when I do it displays a row for every database entry. I understand that I am grabbing all with .all() in the viewpayout = Finances.objects.all() in views.py, but I am unsure of how this should be written to only display one row. How would I display only one row that sums up all of the rows for a column? Any help is greatly appreciated! Below is my code: views.py def finances(request): viewpayout = Finances.objects.all() updatepayout = UpdatePayout() updatewithdraw = UpdateWithdraw() updatecash = UpdateCash() if request.method == "POST": if 'add_payout' in request.POST: updatepayout = UpdatePayout(request.POST) if updatepayout.is_valid(): post = updatepayout.save(commit=False) post.save() return redirect("/finances") else: updatepayout = None if 'bank_withdraw' in request.POST: updatewithdraw = UpdateWithdraw(request.POST) if updatewithdraw.is_valid(): post = updatewithdraw.save(commit=False) post.save() return redirect("/finances") else: updatewithdraw = None if 'add_cash' in request.POST: updatecash = UpdateCash(request.POST) if updatecash.is_valid(): post = updatecash.save(commit=False) post.save() return redirect("/finances") else: updatecash = None return render(request, 'portal/finances.html', {"updatepayout": updatepayout, "updatewithdraw": updatewithdraw, "updatecash": updatecash, "viewpayout": viewpayout}) model.py: class Finances(models.Model): payout … -

Conversion from Markdown to HTML in Django project
I'm on a project which include use of Python, Django, HTML and Markdown. I have to develop a site similar to wikipedia, in fact the project is called encyclopedia. My goal is to make visiting / wiki / TITLE, where TITLE is the title of an encyclopedia entry, to display a page that displays the content of that encyclopedia entry. The encyclopedia entries are CSS Django Git HTML Python (each entry has its own .md file). the problem I have is with the "markdown" library. In practice, I was able to convert the syntax from markdown to HTML but as output I only receive the tags in written format, without them applying their standard style to the content inside them. I am attaching the code I wrote for the conversion and a screenshot of the output I receive. from django.shortcuts import render import markdown from . import util def index(request): return render(request, "encyclopedia/index.html", { "entries": util.list_entries() }) def entry(request, title): content = util.get_entry(title) if content == None: content = markdown.markdown(f'## {title.capitalize()}\'s page has not been found') content = markdown.markdown(content) return render(request, f"encyclopedia/entry.html", { 'title': title, 'content': content }) -
How Can I do PIN Activation, user registration and Authentication in Django
I am working on a Django project where users would have to activate PIN and then register for an event seat. I have done it in such a way that users activate PIN and they are prompted with registration form to secure a seat for an event. And I want to get the Event name, Price, Date, category from the Ticket table. Meanwhile I have a Guest Model that is saving username and pin using an update query during the registration process; using a forms field to request for PIN again (Don't want to repeat this process too). And I have used the pin field as a ForeignKey in the Guest Model so I am getting error that Cannot assign "'384513'": "Guest.pin" must be a "Pin" instance. What is the best way of doing this logic of PIN activation, registration and authenticating a user and getting the Models values associated with his PIN in this case. I was thinking of using the Guest Table to get the information relating to Events, Ticket and Pin Details but no way. See below Models code: class Ticket(models.Model): event = models.ForeignKey(Event, on_delete=models.CASCADE) price = models.PositiveIntegerField() category = models.CharField(max_length=100, choices=PAYMENT, default=None, blank=False, null=False) added_date = …
